Before You Put Clothes Away for the Season, Why Must They Be Washed First? That’s How Next Year’s Yellowing Starts

Last updated: 24 October 2026

Looking clean is not the same as being clean

Even when clothes you’ve worn don’t look dirty, sweat and sebum remain in the fibres. Those things don’t disappear once they’re in the cupboard — they oxidise slowly. When you take them out the next year, the yellow patches at the collar, underarms and front placket are where that comes from. Yellowing that has oxidised and set is much harder to treat than a fresh stain: some can be saved, some can only be improved. So the first rule of seasonal storage is:anything you’ve worn must be washed before it is put away, especially whites and light colours.

The second rule: they must be thoroughly dry before you store them

Clothes and quilts that are not fully dry, put into a space with no air, are a ready bed for mold — next year you open the cupboard to a musty smell and mold spots. Heavy quilts and down are hard to dry through at home: the surface feels dry, but moisture is still inside. Down needs particular care: if you compress it for storage before it is fully dried, the fill clumps and the loft won’t come back the following year.

A few small rules for storage

Hang or store down and wool coats loosely; don’t leave them in a vacuum compress for a long time. Put moisture absorbers in a corner of the cupboard, not directly against the clothes. Leather and luxury pieces don’t go in vacuum bags (see the article on leather care). For starched shirts, make sure they’re pressed before storage; creases that form in the cupboard will set.

A change of season is a good time to send things in

Large items you’ll “wash and put straight away” — coats, down, quilts — are well suited to being done in one go at the change of season: washed, dried through, packed, then stored, so they’re ready to use when you take them out next year.
